Question

A bag contains 4 red marbles, 6 green marbles, and 8 yellow marbles. Find each probability for randomly removing marbles with replacement.

Removing a green marble, then a yellow marble, then a red marble, then a green marble.

Answer 1

Answer: 8/729

Explanation:

There are 18 marbles in total.

• Probability of green: 6/18 = 1/3
• Probability of yellow: 8/18 = 4/9
• Probability of red: 4/18 = 2/9

Multiplying, we get
`(1/3)(4/9)(2/9)(1/3)=8/729`
